Migrating PVE+CEPH to new IP addresses?

[athompso]

I've got a four-node PVE cluster running CEPH (locally, on the PVE nodes).
I see from other posts that in the uncomplicated case, all I would have to do is shut down the nodes, change their IP addresses (/etc/network/interfaces), and reboot them.

But what do I do about nodes that are also running CEPH?
The PVE-to-RBD end looks simple, probably just editing storage.cfg.
Obviously I'd have to change /etc/pve/ceph.conf, each [mon] section... what about the OSDs?

first of all it is strongly suggested to NEVER EVER change the IP address of ceph nodes (more specifically: MONs). Ive you absolutely have to, you can try this: http://ceph.com/docs/master/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address
